SAWMILL SET-WORKS.

Specification of Letters Patent.

Patented Sept. 12, 1916.

Application filed December 24, 1915. Serial No. 68,567. I

To all whom it may concern Be it known that I, GEORGE E. CAMPBELL,

tain new and useful Improvements in Saw mill Set-Works, of which the following is a specification.

My invention relates to an improvement in sawmill set-works, and the object of this invention is to provide means whereby the wear that may occur around the pins in rocker or connecting links will not affect the accuracy of the set-works and to so construct said means that they may be quickly and easily manipulated by the operator.

This invention comprises in the main the following novel and distinctive elements, towit :a yoke loosely mounted on the setshaft or on extended hub of ratchet wheel, which yoke straddles bothcases of the setworks, one of which cases has a ratchettoothed quadrant, and a spring-actuated pawl on the yoke, which normally engages said teeth.

The invention further consists in a pointer carried by the yoke which registers with a graduated scale or figure-strip on one of the cases.

It further consists in a case having two bumpers thereon at diiferent points, one to bump against the yoke, and the other against the other case to limit the backward and forward movements of the cases, and consequently the forward movement of the knees of the set-works, which position the log for the succeeding out.

In the accompanying drawings :Figure 1 is a view in perspective of a saw-mill setworks, showing my improvement applied thereto; Fig. 2 is a plan view; Fig. 3 is a transverse section; Fig. 4: is an enlarged detail of my improved yoke, showing the cases and ratchet-toothed wheels in section; Figs. 5 and 6 are views of the two cases; and Fig. 7 is a view of the yoke.

A, represents my improved yoke, which is loosely mounted on the set-shaft 1, which latter extends throughout the length of the set-works, as is customary, as shown in Fig. l. The yoke straddles the two cases 2 and 3, which latter are loosely mounted on the hub & of the ratchet-wheel 5, which latter is keyed in the usual manner to the set-shaft 1. The two sets of ratchet-teeth of the wheel 5 are normally engaged by the pawls 6, 6, carried by the two cases, which alternately grip and turn the wheel 5 as the cases are oscillated to move the knees 7, which shift the log laterally in the usual manner upon the carrier 8, which feeds the log to the saw (not shown) but as is well understood.

The case 3 carries a quadrant 9, on the upper surface of which the ratchet-teeth 10 are formed, as shown in Figs. 2, 3, 4 and 5. The yoke A has a spring-actuated slidepawl 12, which normally engages these ratchet-teeth, as shown in Fig. 4c, and which is controlled by hand-lever 13, which latter is also employed to adjust the position of the yoke with respect to the ratchet-toothed quadrant on the case 3, according to the thickness of the stock to be cut.

The case 2 has two bumper-stops thereon, one of which, namely bumper-stop 14, is shown adjustable, and the other stop 15 fixed, although it is evident that both might be adjustable. The stop 14 is in position to be struck by the case 3, and the stop 15 is in position to strike the yoke in the extreme movements of the two cases, and the adjustment of the yoke through its pawl 12 engaging the ratchet-teeth 1O regulates the throw of these cases, and consequently the moveinent of the knees and the lateral feed of the The case 3 is provided with a graduated scale 16, as shown in Fig. 2, and the yoke A carries a pointer 25 which registers in line with the scale, by which the operator gages the thickness of the board to be cut.

The set-lever 17 is secured on the rockshaft 18, and the latter carries arms 19 and 20, which extend in opposite directions, and from which the connecting-rods 21 and 22 extend to the cases 2 and 3, respectively, as shown in Fig. 3.

In the operation of the set-works, the operator manipulates the hand-lever 13 to remove the pawl from the ratchet-teeth 10 on the quadrant 9 of the case 3. He then pushes the yoke forward or backward, as necessary to bring the pointer opposite the mark on the graduated scale corresponding to the thickness of the board to be out. He then swings the hand-lever to position to allow the pawl carried by the yoke to engage the ratchet-teeth opposite. The spring holds the pawl firmly against the ratchetteeth, after the yoke is thus set, thereby E. H. ELDER.

SUPPORT AND CONFIN ER FOR PAPER PADS.

Application filed October 25, 1913.

To all whom it may concern:

Be it lmown that I, EDWARD H. ELDER, a citizen of the United States of America, and resident of Chicopee, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Supports and Confiners for Paper Pads, of which the following is a full, clear, and exact description.

This invention for supports and confiners for pads or superimposed leaves of paper, is described hereinbelow 'in conjunction with the accompanying drawings and is defined in the claims.

In the drawings':Figure 1 is a perspective view of the paper holding and supporting device. Fig. 2 is a sectional view through the same from its hinged rear, to its forward end. Fig. 3 is a sectional view through the hinge, and Fig. 4 is a perspective View of parts comprised in the hinge, some thereof being in separated relation.

The device to which this invention relates comprises a base plate A, a clamping plate connected to the base plate by a spring hinge, the location of which is indicated by C, which is adapted to bind and hold the stub end portions a of a plurality of sheets of paper, oftentimes made as a pad, or at least having the stub ends thereof connected, and a cover plate D hinge-connected to the clamping plate.

The principal object of the present invention is to provide a construction of spring hinge for uniting the clamping plate to the base plate which is externally of a smooth continuous cylindrical form and consequently devoid of protuberances, projections or uneven portions, such as have heretofore been found in devices of the same general character, and which have proved disadvantageous and objectionable, firstly as preventing the base plate from lying perfectly fiat on a desk or other support therefor and, secondly, as present ng means to result in scratching or njuring the support.

The object of the invention, furthermore, is to provide in the device a spring hinge Specification of Letters Patent.

composed of parts of simple, easily produced and inexpensive character, and which are susceptible of rapidrand convenient assemblage.

Further referring to the drawings, (in descrlbing the device precisely as it is usually constructed,) G G represent two outer cylindrical members, and J an intermediately related cylindrical member in axial alinement and separation. The intermediate cylindrical member has its end portions 6 b of reduced diameter; and such end portions have transverse slots cZ therethrough. The cylindrical members G G have similar transverse slots 6 within their inner ends, while their outer ends, made with head enlargements 7, have screw driver slots g.

M M represent a pair of helical springs having at each end the end portions of the w re from which the coil spring is made bent into eyes 2', which are engaged in the cross slots (Z and e of the cylindrical blocks or plug-like pieces J and G G.

The springs located between the cylindrical pieces J and G G are inclosed by tubular sheath sections 70 7c of diameter externally corresponding to that of the body portion of said pieces J and G, the same being telescopically engaged at their extremities with the portion 6 of the intermediate cylindrical member which is of the reduced diameter.

- The cylindrical plug-like pieces G G and I J and the tubular sheath sections is which inclose and form a protection for the helical spring engaged with the intermediate and outer cylindrical pieces, present from end to end of the length of the combined parts the aspect of a cylindrical bar of uniform diameter throughout.

The base plate has at the middle portion of its end a tubular extension m of considerable axial length, and it has at different portions of the length of its edge and in separation from the tubular hinge extension m additional shorter tubular extension, m

The clamping plate B has the plurality of substantially similar and correspondingly diametered tubular extensions 0 '0
